Claims.

This invention relates to the art of box makmg, and particularly to the attachment of the lid to the box'.*

This application constitutes a division of our 5 agaslication Ser. No. 39,556, filed September 7,

The invention constitutes an improvement over the invention disclosed in our earlier Patent No. 1,970,580. It was a feature of the patent just noted that the lid of the box, which was preferably formed of laminations of cardboard, was provided with a strong strip of paper or woven material or the like flexible element extending laterally of the edge of the lid, from anchored l5 relation between laminations, and, preferably,

closer to one surface of the lid than to the other, to form what was designated as an easel strip, which was arranged to form a substantially permanent strong flexible bond between the lid and the rear wall of the associated box body, after the conventional hinge strip had been ruptured, as was an incident of bending the lid about the rear wall of the box for easel display purposes.

This was in contrast to the lid and box combinations of the prior art in which the rupturing of the hinge strip usually tore the lid completely from the box body, among other undesirable features thereof.

It was a feature of the invention disclosed in 30 that patent that the so called easel strip emerging from the lid edge when folded properly was laid against the greater portion of the lid edge in the assembly of the lid and box, without any coating of paste or cement, so that it was free 35 to flex or otherwise adjust itself to various lid dispositions. In the illustrative manner of assembly noted in that patent it was suggested that the free edge or end of the easel strip would be pasted and secured adhesively to the 40 upper edge and upper inner surface of the rear wall of the box, and that the hinge piece or strip was similarly pasted and caused to overlie and be adherent to the upper edge of the rear wall, as well as to the portion of the easel strip ad- 45 herent to the upper inner surface of the rear wall. From the standpoint of efficiency and economy in assembly, as well as of enhancement of the long lifeof the completed box, the invention herein marks an advance.

50 It is among'the objects of this invention; to provide a lid and box assembly including an easel strip, in which the easel strip of the lid may be held in' anchored relation to the box without prepasting the. easel strip; to provide an easel 55 trip and, binge; strip combination with a lid in which the hinge strip alone is pasted or coated with adhesive; to improve generally the art of boxes; to improve the construction of boxes with a decrease in the costs thereof; to provide an improved method of associating lids and boxes; to 5 provide an improved method of forming lids and associated easel strips; and many other objects and advantages as will become more apparent as the description proceeds.

In carrying out one phase of the invention in. lo a preferred but illustrative manner, the easel strip is applied to the box wall without a direct coating of adhesive, and is anchored thereto by an overlying adhesive bearing strip engaging the easel strip and the wall surface.

In the accompanying drawings:

Fig. 1 represents a perspective of an assembled box according to the preferred form of the invention, with parts of the lid, and the various strips securing the lid and box together, broken away to show the relationships,

Fig. 2 represents a'perspective of a detached lid according to the preferred form of the invention, showing the relationships of the easel, hinge, and label strips of the lid,

Fig. 3 represents a fragmentary section taken on line 3-3 of Fig. 2, showing the adhesive'coatings as dotted lines on the hinge strip and label, but indicating that the easel strip is free from an adhesive coating,

Fig. 4 represents a fragmentary section of, a box wall and the lid to be associated therewith, showing in dotted lines a form of plunger in position to engage the detached lid carrying the attached easel and hinge strip whereby relative movement of the box and lid may be secured,

Fig. 5 represents the same parts as in Fig. 4, in the next stageof association of the parts, with the lid relatively pushed downwardly into substantial horizontal alignment with the upper edge of the box rear wall, with the easel strip bent up across the edge of the lid to contact with the coated surface of the hinge strip and to rest upon the upper edge of the rear wall, with a roller, indicated in dotted lines, ready to wipe the assem- 5 bled easel and hinge strips downwardly upon the rear wall of the box,

Fig. 6 represents a later stage. in the association of the parts according to Figs. 4 and 5, in which the dotted roller is shown in two different positions to indicate the wiping completion of the assembly,

Fig. '7 represents a fragmentary section of a partially assembled lid and box, with the lid,

easel and hinge strips of Figs. 4, 5, and 6, overlain,

covered and concealed by the pasted label, which also contributes to the anchoring assembly of the whole,

Fig. 8 represents an assembled lid and box with the lid in closed position, with the decorative edge-covering rear border or strip attached in adherent relation to the rear part of the other surface of the lid, to the exposed lamination of the lid beyond the easel strip, to the easel strip and to the rear wall of the box,

Fig. 9 represents the fragmentary section of the box of Fig. 8, with the lid opened, as when the lid is used as a handle for the composite box, prior to rupturing'of the hinge strip,

Fig. 10 represents a fragmentary section of the parts when the hinge piece has been ruptured to permit disposition of the lid substantially parallel to the box rear wall when the box is to be used as an easel display, and

Fig. 11 represents an edge elevation of the lid Of Fig. 3.

Referring now to Figs. 1, 2 and 3, it..will be observed that the lid 9 of the invention iscomprised preferably of at least two laminations, as I and I I, of which preferably the first mentioned is perceptibly thicker than layer II, and preferably comprises at least twice the material of the thinner sheet. In the formation of the composite lid, it is preferable that the thick layer Ill be provided, which then is adhesively engaged by the easel strip I2, to be described, and that then the thin lid layer or lamination II, coated with adhesive, is superposed upon the thick layer and easel strip and pressed and rolled into adherent unity of structure. The easel strip of the preferred form is of any suitable material such as flem'ble woven material or the like or fairly strong paper, with or without reinforcements, and is firmly anchored between the laminations of the lid. It is preferred that theea'sel strip be appreciably less in length than the length of the lid, so that its lateral edges 1 are inwardly spaced from the lateral edges 8 of the lid. It will be observed in the cited figures that whereas the anchored edge of the easel strip I2, engaged between laminations is suitably adherent therein, there is no adhesive in the preferred form of the easel strip I2, on either of its exposed surfaces at its free edge. It is preferred that the lids be made up in quantities preformed with the easel strips attached, as by a machine such as is shown for instance, an application 64,760, filed February 19, 1936.

The next step in the assembly of the structure is the provision of the hinge strip I 5. Preferably this strip is adhesively coated over one entire surface as at I6, and is caused to adhere in part to the surface of the lid comprised by the exposed area of the thicker lamination I0 thereof with the remainder of the coated strip extending laterally of the lid in substantial parallelism with the easel strip I2. The hinge strip is illustratively and preferably longer than the easel strip with which it is disposed in parallelism, as shown in Fig. 4, both in its extension perpendicularly to the edge of the lid, defined by edge I3, and to the longitudinal extent as defined by side edges I4, as well, as indicated in Figs. 1 and 2. It is pointed out that in some cases the hinge and easel strips may be of the same approximate area when in place, or that the extension of one over the other may be in but one direction, instead of the two that is preferred.

Referring now to Fig. 4, in the preferred form,

the lid 9, suitably supported, is engaged by the plunger indicated at I! in dotted lines, while the rear wall I8 of the box, having the upper edge 20 is also suitably supported and the parts are arranged for such relative vertical motion, usually by causing plunger I! to push lid 9 downwardly relative to the box wall, that they move to the position shown in Fig. 5. In this figure the'relatively unpasted easel strip I 2 has been bent upwardly across the edge I9 of the lid, and then laterally to overlie the upper edge 20 of the box wall I8, and into contact with the coated pasted surface of the hinge strip I and the assembly is then in position for the next step in the assembly; Asshown in Fig. 5, this effectively shortens the easel strip and thus contributes to the outward extension of the free edge I3 of the hinge strip I5, over the outer edge 6 of easel strip I2, if this is desired. At this juncture, as shown in said Fig. 5, a roller, indicated by dotted lines at 2|, begins vertical relative movement with the rear wall I8, to wipe the now contacting free marginal edges of the easel strips downwardly over the upper edge and inner surfaces of the Wall.

As shown in Fig. 6, and as will be clear from the description, the fact that the easel strip has no paste on its under surface which is in contact with the upper wall edge 20 and rear surface 29 of wall I8, prevents the easel strip from being directly adherent thereto. and 11, however, the fact that in the preferred form, the pasted hinge strip I5 extends longitudinally beyond at least one edge of the easel strip and laterally beyond edge 6 thereof, and

engages both the easel strip, and the upper surface 20 and inner surface of the rear wall I8 of the box beyond the edge I4 of the easel strip forms a most effective anchor for the easel strip. Manifestly the hinge strip may be as long as the width of the lid so as to cover the entire edge I9,

if desired, but it will be understood that in the with its strength and the adhesive used. It will be observed that label 23 extends longitudinally beyond both the easel and hinge strips as at 24, and laterally it extends as at 25. It will be clear that label 23, if of suitable strength could form As shown in Figs. 6

It will be the anchoring device to attach both the hinge and easel strips, if, for any reason, it were preferred to make the hinge strip of the same substantial area and contour as the easel strip in the assembled relation of the parts. As noted the preference is that the hinge piece form the anchoring element for the easel strip. As an added advantage it is pointed out that the hinge strip and label strip, both or either, in accordance with particular demands, in extending longitudinally beyond the lateral confines of the easel strip, form means for anchoring the easel strip to the upper wall surface 20, as well as to the inner surface of the wall I8. An external decorated border or supplemental hinge strip 26 completes the lid' and box assembly being externally adherent to the lid edge I9, the easel strip, the outer surface of the rear wall, and the upper surface of lid 9.

"The advantages in cheap assembly will be obvi- 7 5 ous to those familiar with the problems attaching to the box manufacturing industry. It may be observed that the procedure outlined herein is helpful in maintaining the life of the paper products used in the lid and easel and hinge strips. It may occasionally happen that the easel strip, if subjected to pasting upon both sides of certain portions spaced from the edge of the lid, may dry out and be prone to cracking or other undesirable action, which this assembly obviates.

We claim:

1. A method of associating lids with boxes which consists in providing an easel strip and a hinge strip anchored to the lid with the anchored portions in spaced relation, then in disposing the lid and a wall of the box in juxtaposition, then in securing relative movement of the lid and wall in the plane of the wall whereby the easel and hinge strips are brought into contact on top of said Wall, then securing the contacting easel and hinge strip in engagement with the inner surface of said Wall.

2. A method of associating lids and boxes which consists in applying an adhesively coated 5 hinge strip to a surface of a lid which has an easel strip anchored to project laterally in substantially parallel spaced relation to said surface, in bringing the free end of the easel strip across the lid edge to contact with said hinge strip, and

then in securing the contacting easel and hinge strips to a box wall.

3. In a method of associating cardboard lids and boxes, the steps which comprise providing a lid with an easel strip projecting laterally from an edge between the outer surfaces of the lid and then in securing a hinge piece projecting laterally of the lid on a surface thereof, then in bending the easel strip across the edge of said lid into contact with the hinge piece, and then securing the contacting portions of the easel and hinge strips together.

4. A method of associating lids with boxes which consists in providing a lid with an anchored laterally extending easel strip and with a laterally extending hinge strip anchored to the lid in spaced relation to the easel strip, then in bending the easel strip across the edge of such lid into contact with the hinge strip with an edge of the hinge strip extending beyond the easel strip to provide an exposed hinge strip surface, then in securing the contacting easel and hinge strips to a box wall with the said exposed surface in contact with and secured to said box wall.

5. A method of associating lids with boxes which consists in providing a lid with an anchored easel strip extending laterally from an edge thereof, then in securing a hinge strip to the surface of the lid projecting from the same edge thereof spaced from the easel strip, then in juxtaposing the lid and the wall of a box, then in relatively moving the lid and wall substantially in the plane of the Wall whereby the easel strip is bent across the edge of the lid and into contact with the hinge strip to expose a surface thereof, then in
